As part of the project for the new Bogportalen platform, the format for delivering metadata to Bogportalen is being changed from an older Bogportalen format to the standard ONIX format.
ONIX is an international standard for book data, already used by several of DBK’s customers in other contexts, which makes it appropriate for DBK to adopt the standard as well.
You can read more about ONIX in general at Editeur.
From the very extensive list of fields in the full international standard, DBK is engaging in dialogue with customers who both supply and receive metadata, to define a limited set of fields that ensures the data is both relevant and useful.
A webinar about metadata from DBK in ONIX has been held. Watch the webinar here.
Implementation timeline
All customers supplying and receiving metadata to and from Bogportalen were formally notified of the change at the end of August 2025.
The timeline below shows the implementation schedule for the new ONIX metadata delivery format to Bogportalen.

First draft of fields. Used for dialogue with DBK customers regarding the final fields. Please note that the format is subject to approval by DBK’s customers and has not yet been finally approved. |
In the document below, is a list with all the fields that are available in the current data to Bogportalen, and what fields are included in the new format. Use the list to verify if the fields not in scope are used for something important in your systems and processes.
Green = Included in both current and new data delivery
Yellow = Not included in the new data delivery, but under consideration for a future update
Red = Not included and not planned for future data deliveries
Thema codes (27)
The default classification of books in Onix, is Thema codes.
Bookstore classification (27,24)
Although Thema is the standard classification for books, the older format ‘Boghandlernes varegrupper’ (Booksellers’ product groups) is also included as an optional proprietary subject scheme “24” within “27”. Since ‘Boghandlernes varegrupper’ is still widely used in the Danish book industry, it is therefore supported in the ONIX fields used by DBK.
